I've compiled my applications with profiling support, and I know that internally it's generating the profiling info, but when I exit the application the output files aren't anywhere on the memory stick :-\
Has anyone managed to get profiling working on the PSP?
If you want gprof support it's gonna have to be added to the PSP GCC backend, sorry.
TyRaNiD did add some PSP hardware profiling support to PSPSDK, but you're going to have to write tools to parse that data (or otherwise handle it yourself).
